Abstract

 The effect of the avearage warp yarn float, weft yarn density and the type of dyes on, fabric colour properties was investigated. Five different avearage warp yarn floats, each of three different weft yarns density were woven then dyed with three different type dyes which are direct, vat, and reactive dyes. 
A total of 45 different specimens each represents different case were tested to obtain psychrometric chroma (C), hue angle (H) and lightness (L), the results showed that both weft density and warp average float have a remarkable effect on fabric colour properties. 
It was found that, in general, the increasing of the average float lead to decreases the hue angle (H) and the lightness (L) which give an increasing in psychrometric chrome. But the increasing of the weft yarn density lead to increasing in the hue angle (H) and lightness (L) which give a decreasing in the psychometric chroma (C).
